Precautions for Safe Use
Precautions for Safe Use
Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse
affects on the performance and functions of the product. Not doing so may occasionally result in unexpected events. Use the product within specifications.
• The product is designed for indoor use only. Do not use or store the product in any of the following
locations.
Locations directly subject to heat radiated from heating equipment.
Locations subject to splashing liquid or oil atmosphere.
Locations subject to direct sunlight.
Locations subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).
Locations subject to intense temperature change.
Locations subject to icing and condensation.
Locations subject to vibration and large shocks.
• Use and store the Digital Controller within the rated ambient temperature and humidity.
Gang-mounting two or more Digital Controllers, or mounting Digital Controllers above each other may
cause heat to build up inside the Digital Controllers, which will shorten their service life. In such a
case, use forced cooling by fans or other means of air ventilation to cool down the Digital Controllers.
• To allow heat to escape, do not block the area around the product. Do not block the ventilation holes
on the product.
• Be sure to wire properly with correct polarity of terminals.
• Use the specified size of crimped terminals (M3, width of 5.8 mm or less) for wiring. To connect bare
wires to the terminal block, use copper braided or solid wires with a gage of AWG24 to AWG18
•
•
•
•
•
•

(equal to a cross-sectional area of 0.205 to 0.8231 mm2). (The stripping length is 6 to 8 mm.) Up to
two wires of the same size and type, or two crimped terminals can be inserted into a single terminal.
Do not wire the terminals that are not used.
To avoid inductive noise, keep the wiring for the Digital Controller's terminal block away from power
cables that carry high voltages or large currents. Also, do not wire power lines together with or
parallel to Digital Controller wiring. Using shielded cables and using separate conduits or ducts are
recommended.
Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular,
motors, transformers, solenoids, magnetic coils or other equipment that have an inductance
component).
When a noise filter is used at the power supply, first check the voltage or current, and attach the noise
filter as close as possible to the Digital Controller.
Allow as much space as possible between the Digital Controller and devices that generate powerful
high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.
Use this product within the rated load and power supply.
Make sure that the rated voltage is attained within 2 seconds of turning ON the power using a switch
or relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions
may occur.
Make sure that the Digital Controller has 30 minutes or more to warm up after turning ON the power
before starting actual control operations to ensure the correct temperature display.
When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Digital Controller. If power is turned ON for the Digital Controller before turning
ON power for the load, self-tuning will not be performed properly and optimum control will not be
achieved.
E5@C Digital Temperature Controllers Communications Manual (H175)
Precautions for Safe Use
• A switch or circuit breaker must be provided close to the Digital Controller. The switch or circuit
breaker must be within easy reach of the operator, and must be marked as a disconnecting means for
the Digital Controller.
• Wipe off any dirt from the Digital Controller with a soft dry cloth. Never use thinners, benzine, alcohol,
or any cleaners that contain these or other organic solvents. Deformation or discoloration may occur.
• Design the system (e.g., control panel) considering the 2 seconds of delay in setting the Digital
Controller’s output after the power supply is turned ON.
• The output will turn OFF when you move to the initial setting level. Take this into consideration when
performing control.
• The number of non-volatile memory write operations is limited. Therefore, use RAM write mode when
frequently overwriting data, e.g., through communications.
• Use suitable tools when taking the Digital Controller apart for disposal. Sharp parts inside the Digital
Controller may cause injury.
• Do not connect cables to both the front-panel Setup Tool port and the top-panel Setup Tool port at the
same time. The Digital Controller may be damaged or may malfunction.
• Do not exceed the communications distance that is given in the specifications and use the specified
communications cable. Refer to the E5@C Digital Temperature Controllers User’s Manual (Cat. No.
H174) for the communications distance and cable specifications.
• Do not turn the power supply to the Digital Controller ON or OFF while the USB-Serial Conversion
Cable is connected. The Digital Controller may malfunction.

Functional Upgrades
Functional Upgrades Ver.1.1
Support for programless communications and component communications was added. The functional
upgrades that were made are described in this section.
Refer to Section 6 Programless Communications and Section 7 Component Communications in this
manual for details on the functional upgrades.
Programless Communications
With programless communications you can read and write E5@C parameters or start and stop the
E5@C from a Programmable Controller. Communications with the PLC are performed automatically by
the E5@C, so there is no need to program communications.

New Models
New Models Ver.2.0
E5EC/E5AC Digital Controllers with position-proportional control and E5AC Digital Controllers were
added.
Precautions for Correct Use
The CX-Thermo does not support the new functionality as of May 2012. To use the CX-Thermo,
first set other parameters from the CX-Thermo and then set the parameters for the new
functionality from the E5@C Controller. If the set values of the parameters are read from the
CX-Thermo after setting parameters for the new functions, the set value of the Protocol Setting
parameter will be initialized in the CX-Thermo. Also, if the set values of the parameters that were
previously read are written to the E5@C Controller, the initialized set value of the Protocol Setting
parameter will be written to Controller. As a result, the new functionality will be disabled.

Introduction
The program for the communications functions is created on the host (personal computer, PLC, or other
type of communications master), and the E5@C's parameters are monitored or set from the host.
Therefore, the description provided here is from the viewpoint of the host.
CompoWay/F is OMRON's standard communications format for general serial communications. This
format uses a standard frame format as well as the well-established FINS* commands used for
OMRON's PLCs. Therefore, it can simplify communications between components and the host.
*
FINS (Factory Interface Network service)
The FINS protocol provides message communications between controllers in OMRON FA networks.
Modbus is a standard communications control method that conforms to the Modicon Company's
RTU-mode Modbus Protocol (PI-MBUS-300 Revision J). Modbus is a registered trademark of
Schneider Electric.
It supports functions equivalent to the CompoWay/F Read Variable Area, Write Variable Area, Operation Command, and Echoback Test functions.
The E5@C supports the following communications functions.
• Reading/writing of parameters
• Operation instructions
• Selection of setup levels
Communications are subject to the following condition:
• Parameters can be written only when the Communications Writing parameter is set to ON (enabled).

Description of Communications Parameters
When communications parameter settings have been changed, the new settings must be enabled by
resetting the Controller.
• Protocol Setting (psel)
The communications protocol can be selected. Set CompoWay/F or Modbus.
1-1 Overview of Communications Methods
1-1-8

• Communications Baud Rate (bps)
This parameter is for setting the baud rate for communications with the host. The communications
baud rate settings are as follows: 9.6 (9600 bps), 19.2 (19200 bps), 38.4 (38400 bps) or 57.6 (57600
bps)
• Communications Data Length (len)
This parameter is for setting the number of communications data bits. Set either “7 bits” or “8 bits.”
• Communications Stop Bits (sbit)
This parameter is for setting the number of communications stop bits. Set either “1” or “2.”
• Communications Parity (prty)
This parameter is for setting the communications parity. Set the parity to “none,” “even,” or “odd.”
• Send Data Wait Time (sdwt)
The send data wait time is the delay from when the Controller receives a command from the host
computer until it returns a response. If the response is returned too quickly, the host computer may
not be able to receive the response. Change the send data wait time as required. To increase the
response speed for communications, reduce the send data wait time. The send data wait time can
be set in 1-ms increments between 0 and 99 ms. The default is 20 ms.
E5@C Digital Temperature Controllers Communications Manual (H175)
1-7
1-1-8 Description of Communications Parameters
• Communications Unit No. (u-no)
This parameter is for setting a unique unit number for each of the Digital Controllers. This unit number is set so that the host can identify the Digital Controller when communications are carried out
with the host. The unit number can be set to an integer value between 0 and 99. The default is “1.”
When two or more Digital Controllers are used, do not set the same unit number. Doing so will prevent normal operation.

• Communications Writing
Set the Communications Writing parameter to "ON: enabled" or "OFF: disabled" with the related
information setting. The setting can be accepted in both setup area 0 and setup area 1. An
operation error will occur, however, if enabling or disabling communications writing is set for an
event input.
• RUN/STOP
Set control to “run” or “stop” with the related information setting. The setting can be accepted in
both setup area 0 and setup area 1. An operation error will occur, however, if RUN/STOP is set for
an event input.
E5@C Digital Temperature Controllers Communications Manual (H175)
2 - 17
2 CompoWay/F Communications Procedures
• Multi-SP
Set eight set points beforehand in the adjustment level so that you can switch to a desired set
point. The setting can be accepted in both setup area 0 and setup area 1. An operation error will
occur in the following situations.
• When AT is being executed.
• When the Number of Multi-SP Points parameter is set to OFF.
• When the Number of Multi-SP Points parameter is not set to OFF, but Multi-SP No. Switch is
set for an event input.
• AT Execute/Cancel
Set AT (auto-tuning) to “execute” or “cancel” with the related information setting. This command
can be accepted in setup area 0 only. An “operation error” will be generated in the following
instances:
• When the RUN/STOP parameter is set to “stop”
• When the command is executed in “setup area 1”
• When ON/OFF control is being used
• When 40% AT is specified during 100% AT execution.
• When 100% AT is specified during 40% AT execution.
A parameter error will occur if 40% AT is specified during heating and cooling control or floating
position-proportional control.
Note: If the same type of AT execution is specified during AT execution (e.g., if 100% AT is specified during
100% AT execution), the AT will not be restarted and the operation will end in normal completion with
no processing.
• Write Mode
Set either the backup mode or RAM write mode with the related information setting. The setting
can be accepted in both setup area 0 and setup area 1.
The number of non-volatile memory write operations is limited. Therefore, use RAM write mode
when frequently overwriting data.
Write mode
Backup mode
RAM write mode
Description
The data is written to non-volatile memory when the parameters in the
operation/adjustment levels (excluding read-only parameters) are written
by communications.
The data is not written to non-volatile memory when the parameters in the
operation/adjustment levels (excluding read-only parameters) are written
by communications. Parameters can be changed by operating the keys
on the front panel of the Controller.
• When the mode is switched from RAM write mode to backup mode, the parameters in the
operation/adjustment levels (excluding read-only parameters) are written to non-volatile
memory.
• The RAM write mode is enabled only when the Communications Writing parameter is set to
“ON” (enabled).
Consequently, when the Communications Writing parameter setting is changed to "OFF"
(disabled), the parameters in the operation/adjustment levels (excluding read-only
parameters) are written to non-volatile memory even if the mode is set to RAM write mode.
• Save RAM Data
This command writes the parameters in the operation/adjustment levels (excluding read-only
parameters) to non-volatile memory. The setting can be accepted in both setup area 0 and setup
area 1.

E5@C Digital Temperature Controllers Communications Manual (H175)
2 CompoWay/F Communications Procedures
• Move to Setup Area 1
This command moves to “setup area 1” and can be accepted at both setup areas 0 and 1. If the
“initial setting/communications protect” is set to “2,” an “operation error” will be generated, and the
move to setup area 1 will be prohibited.
When this move is carried out from setup area 0, the display indicates the Input Type parameter in
the “initial setting level.” When this operation command is executed in setup area 1, the display will
not change.
• Moving to Protect Level in Manual Mode
When this operation command is issued in manual mode, an “operation error” will be
generated, and the move to the protect level will be prohibited.
• Auto/Manual Switch
This operation command switches the mode to manual mode or automatic mode, based on the
related information setting. This command can be accepted in setup area 0 only. An “operation
error” will be generated in the following instances:
• When the command is executed in “setup area 1”
When the Controller is switched to manual mode, the “manual manipulated variable” will be
displayed. When the Controller is switched from manual mode to automatic mode, the
operation level's first parameter will be displayed. When the Controller is switched to auto
mode while already in auto mode or switched to manual mode while already in manual mode,
the command will be completed normally and the display will not change (the contents will not
be refreshed).
• Writing Auto/Manual Status in Non-volatile memory
The write mode determines whether the auto/manual status is written to non-volatile memory.
Write mode
Backup mode
RAM write mode
Description
When the auto/manual mode is switched by communications, the
auto/manual status is written to non-volatile memory.
When the auto/manual mode is switched by communications, the
auto/manual status is not written to non-volatile memory.
The status can be written with the Controller key operation.
Note: When the auto/manual mode is switched with an operation command through communications
and the Controller is in RAM write mode, the auto/manual status is not stored in non-volatile
memory. Consequently, if the Controller is restarted by performing a software reset or turning the
power OFF and ON again, the auto/manual mode is set to the last saved status.
• Switching to Manual Mode during Auto-tuning
If the mode is switched during auto-tuning (AT), the AT will be cancelled and the Controller will
be switched to manual mode.
• Parameter Initialization
The present settings are returned to the default values and written to non-volatile memory. This
command can be accepted in setup area 1 only. When this command is issued in setup area 0, an

• Software Reset
Restarts processing from the point when power is turned ON. The setting can be accepted in both
setup area 0 and setup area 1.
2 CompoWay/F Communications Procedures
“operation error” will be generated. (These settings are the same as the ones used when “FACT”
is selected for the setting data's set value initialization.)
• Alarm Latch Cancel
The applicable alarm latch can be cleared with the related information setting. The setting can be
accepted in both setup area 0 and setup area 1. An operation error will occur if communications
writing is disabled or if an non-volatile memory error occurs.
• Invert Direct/Reverse Operation
Inverting or not inverting direct/reverse operation can be selected with the related information
setting. The setting can be accepted in both setup area 0 and setup area 1. The related
information specifications are written to non-volatile memory according to the write mode settings.
An operation error will occur in the following situations:
• When AT is being executed.
• When inverting direct/reverse operation is set for an event input.
• When executed in manual mode.
• Program Start
The simple program function can be reset/started with the related information setting. The setting
can be accepted in both setup area 0 and setup area 1. An operation error will be generated if
program start has been set in the event input.
• Setting Areas
Control operation is executed in setting area 0. In this state, you can perform operations that are
permitted only during control or those that cause no problems even if control is in progress. These
operations include reading PVs, writing SPs, and changing RUN/STOP status.
Setting area 0, however, prohibits operations that affect control, including writing data at the initial
setting level. (Reading setting data is always allowed.)
In setting area 1, control operation is stopped. In this state, you can perform operations that are
not allowed in setting area 0. These operations include writing data at the initial setting level.
At power-ON, the Digital Controller is set in setting area 0. To move to setting area 1, use the
"move-to-setting area 1" command. To return to setting area 0, turn the power OFF and ON again,
or use the "software reset" command.

The service function for the relevant
command is not supported.
The command is too long.
The command is too short.
Wrong variable type
The read/write start address is out of range.
The write end address (write start address +
number of elements) exceeds the final
address of the variable area.
The amount of data does not match the
number of elements.
The response length exceeds the
communications buffer size (when the number
of elements is greater than the maximum
number of elements for that service).
• Bit position is not “00.”
• The write data is out of the setting range.
• The command code or related information
in the operation command is wrong.
Variable type “C0” was written to.
• The Communications Writing parameter is
set to “OFF” (disabled).
• Attempted to write to a parameter in setup
area 1 from setup area 0.
• Attempted to write to a protect parameter
from other than the protect level.
• Writing was carried out during AT
execution.
• Processing is not possible by operation
command.
• Non-volatile memory error

Variable Area (Setting Range) List
• For communications using a variable type not enclosed in parentheses in the following table, the set
value is double-word data (8 digits). For communications using a variable type enclosed in
parentheses, the set value is single-word data (4 digits).
• For example, variable type C0 is double-word data (8 digits), and variable type 80 is single-word data
(4 digits).
• Items expressed in hexadecimal in the "Setting (monitor) value" column are the setting range for
CompoWay/F communications. The values in parentheses are the actual setting range. When there
is a section reference for a setting item, refer to that reference for details.

4 Modbus Communications Procedure
4-1
Data Format
The data format complies with the Modbus (RTU) communications protocol, so commands from the
host and responses from the E5@C are contained in data blocks called frames.
The structure of the command and response frames is described below.
In the following explanations, hexadecimal values are expressed by adding the prefix H' before the
number, e.g., H'02. Numbers and alphabetic characters without the H' prefix are ASCII characters.
4-1-1 Command Frame
When using RTU mode, start with a silent interval of at least 3.5 character times and end with a silent
interval of at least 3.5 character times.

Specify the unit number.
The unit number can be set between H'00 to H'63 hexadecimal (0 to 99 decimal).
Specify H'00 for a broadcast transmission. No responses will be returned for
broadcast transmissions.
The function code is a 1-byte hexadecimal code that indicates the type of command
sent from the host device.
This is the text data associated with the specified function code. Specify the required
data, such as the variable address or setting data. (Set in hexadecimal.)
Cyclic Redundancy Check
This check code is calculated with the data from the slave address to the end of the
data.
The check code is 2-byte hexadecimal.
Silent interval of 3.5 character times minimum.
E5@C Digital Temperature Controllers Communications Manual (H175)
4 Modbus Communications Procedure
z CRC-16 Calculation Example
Messages are processed one byte at a time in the work memory (a 16-bit register known as the
CRC register).
(1) The CRC register is initialized to H’FFFF.
(2) An XOR operation is performed on the content of the CRC register and the first byte of the
message, and the result is returned to the CRC register.
(3) The MSB is packed with zeroes and the CRC register is shifted 1 bit to the right.
(4) If the bit shifted from the LSB is 0, step 3 is repeated (next bit-shift processing).
If the bit shifted from the LSB is 1, an XOR is performed on the content of the CRC register
and H’A001, and the result is returned to the CRC register.
(6) CRC processing continues to the end of the message, as XOR operations are performed
on the content of the CRC register and the next byte of the message, step 3 is repeated,
and the result is returned to the CRC register.
(7) The result of the CRC calculation (value in the CRC register) is appended to the last byte of
the message.

4 Modbus Communications Procedure
4-3
Variable Area
The variable area is the region of memory used to exchange data with the E5@C through communications.
Operations such as reading the process value and reading/writing parameters are performed on the
variable area.
On the other hand, operation commands do not use the variable area.
E5@C
Microcomputer
Variable area
Read/write
When accessing the variable area, the position of a variable in the variable area is specified with a word
identifier, area number, and address in the area.
z Addresses
An address is appended to each of the variable types. Express addresses in 2-byte hexadecimal
and append them for the specified access size.
z Number of Elements
The number of elements is expressed in 2-byte hexadecimal. The setting range for the number of
elements varies according to the command.
Four-byte Mode
One element uses 2 bytes of data, so specify two-element units. Reading and writing in 4-byte units
is executed by specifying an even address and specifying the number of elements in multiples of 2.
Two-byte Mode
One element uses 2 bytes of data, so specify one-element units. Reading and writing in 2-byte data
units is executed by specifying 1-element units.
z Set Values
The values read from the variable area or written to the variable area are expressed in hexadecimal,
ignoring the decimal point position. (Negative values are expressed in 2's complement format.)
Example: D'105.0 → H'0000041A
The variables are 4-digit or 8-digit hexadecimal values. Negative values are expressed in 2's
complement format. The values are hexadecimal values with no decimal point indication.
For example, if the E5@C's process value is read in 4-byte mode when the process value is 105.0,
the read value will be H'0000041A (105.0 → 1050 → H'0000041A).

Variable Area (Setting Range) List
• Four-byte Mode
One element uses 4 bytes of data (H'00000000 to H'FFFFFFFF), so specify two-element units.
Reading and writing in 4-byte units is executed by specifying an even address and specifying the
number of elements in multiples of 2.
• Two-byte Mode
One element uses 2 bytes of data (H'0000 to H'FFFF), so specify one-element units. Reading and
writing in 2-byte data units is executed by specifying 1-element units.
The following table lists the variable area. Items expressed in hexadecimal in the "Setting (monitor)
value" column are the setting range in the Modbus specifications. Values in parentheses "()" are the
actual setting range.
When there is a section reference for a setting item, refer to that reference for details.

Introduction
With programless communications you can read and write E5@C parameters or start and stop the
E5@C from a Programmable Controller (PLC). Communications with the PLC are performed automatically by the E5@C, so there is no need to program communications.
The E5@C automatically reads
and writes PLC memory.

6-1-1 Introduction
• You can connect to an OMRON CS/CJ-series or CP-series PLC or to a Mitsubishi Q-series or
L-series PLC.
• Up to 13 E5@C parameters can be assigned for reading and up to 13 E5@C parameters can be
assigned for writing in PLC memory. Each E5@C Controller is allocated 30 words of PLC memory. (A
total of 480 words are allocated if 16 E5@C Controllers are connected.)
• You can set the PLC memory area and addresses to use for programless communications.
• You can copy settings between E5@C Controllers to greatly reduce setup work and setting mistakes.

6-1-3
Operation for Programless Communications
Programless communications are performed in the following order of communications unit numbers.
0 (master) → 1 → 2 → ... → Highest communications unit number → 0 → 1...
The master (the Controller with communications unit number 0) starts programless communications
approximately five seconds after the power supply to it is turned ON. (Communications are not performed until the power supply to the master is turned ON.) When the master starts communications, the
slaves (the Controllers with a communications unit number other than 0) also start communications.
After communications have started, they will continue for the remaining E5@C Controllers even if one or
more of them (including the master) stop. However, the communications cycle will increase while waiting for communications from the stopped E5@C Controllers.
6-1-4
Timing of Turning Power ON and OFF
z Turning ON Power
Turn ON the power supply to the E5@C Controllers either after the PLC or at the same time as the
PLC. The following may occur if the power supply is turned ON to the PLC after programless
communications have started.
• The PLC may detect a communications error.
• The Response Flag may change to eeee once at startup.
z Turning OFF Power to Mitsubishi PLCs
To turn OFF the power supply while communications with the PLC are active, change the E5@C
Controller to the initial setting level first, and then turn OFF the power supply. If you turn OFF the
power supply to an E5@C Controller during programless communications, the PLC may detect a
communications error.
z Restarting only the E5@C Controllers
Use the following procedure to restart the E5@C Controllers.
1
Move all of the E5@C Controllers to the initial setting level.
2
Cycle the power supply in order to the slaves (the Controllers with a communications
unit number other than 0) and then to the master (the Controller with a communications
unit number of 0), or change the slaves and then the master back to the operation level.
Note: If the above procedure is not followed and the PLC detects an error, clear the error from the program in the
PLC.

Communications Unit No. and Communications Baud Rate
Always assign communications unit numbers in order starting from 0. Do not skip any numbers. Communications unit number 0 is for the master. The numbers from 1 on are for the slaves. We recommend
a communications baud rate setting of 57.6. Set the same communications baud rate for all of the
E5@C Controllers and the PLC. (Setting the PLC is required only for programless communications.)

Two areas are used in PLC memory by the E5@C, an upload area and a download area. The upload
area is used to monitor the process value, status, and other information from the E5@C. The download
area is used to write the set point, alarm values, and other values to the E5@C.

The status that is given at this address is used in the PLC to check
the operation of programless communications.
Information from the E5@C, such as the PV or status, is set at
these addresses. The parameters that are actually used are set in
the upload settings.
This flag is used to control programless communications.
The operation command that corresponds to the code is sent.
The set values at these addresses are written to the E5@C, such
as to the set point or alarm values. The parameters that are
actually used are set in the download settings.
The Response Flag, Communications Status, Request Flag, and Operation Command Code all have
special functions that cannot be changed. Refer to the following sections for application methods.

Last address: First address + (highest communication unit number + 1) × 30 − 1
Example: The following example is for three E5@C Controllers (highest communications
unit number = 2). The first address is set to 100.
Last address = 100 + 3 × 30 − 1 = 189

Receive Data Wait Time
The receive data wait time is the time that the E5@C waits for a response from the PLC (or, for component communications, from an E5@C slave). You can normally use the default setting.
If you change the receive data wait time, the time at which programless communications start will
change after the power supply is cycled. Use the following formula to calculate the start time.
Start time = Approx. 1 s + Receive data wait time × 4
Example: For the default setting of 1,000 ms, the start time is approximately 5 s.

You can copy the settings of all parameters except for the Communications Unit No. parameter from the
master (i.e., the Controller with communications unit number 0) to one or more of the slaves (i.e., the
Controllers with communications unit numbers other than 0). Copying parameters is possible only
between Controllers with the same model number. You also cannot copy parameter settings to a Controller with a version that is older than the version of the master. All of the slaves are automatically reset
after the copying operation is completed. Make sure that the system will not be adversely affected
before you copy parameter settings.

Copying Procedure When Replacing a Controller
z Replacing a Slave (i.e., a Controller with a Communications Unit Number
Other Than 0)
(1) Replace the E5@C, wire it, and then turn ON the power supply.
(2) Change all of the E5@C Controllers to the initial setting level and stop programless
communications. The above step is not required for component communications.
(3) Set the Communications Unit No. parameter and Communications Baud Rate
parameter (57.6) in the new E5@C Controller and then return to the operation level.
(4) Copy the parameter set values from the master to the new E5@C Controller by
specifying the number of the Controller.
z Replacing the Master (i.e., the Controller with a Communications Unit
Number of 0)
(1) Perform steps 1 and 2 in the above procedure.
(2) Record the communications unit number and communications baud rate of the slave
with communications unit number 1, and then temporarily change the
communications unit number to 0 (master). Do not return to the operation level after
you change the communications unit number.
(3) Set the Communications Unit No. parameter and the Communications Baud Rate
parameter of the new E5@C to the values that you recorded, and then change to the
operation level.
(4) Copy the parameter settings from the temporary master, specifying
communications unit number of the new E5@C.

Writing can be enabled and disabled from the PLC (or, for component communications, from the E5@C
master). The Communications Writing parameter is normally left ON (enabled). However, if it is necessary to change set values from the display section of the E5@C in an emergency, temporarily change
the setting to OFF (disabled). If you disable communications when writing is being performed from the
PLC, an error will occur in the PLC. (An error code will be set in the Response Flag in PLC memory.) If

The Response Flag gives the number of the download setting where the error occurred. If more than one
error occurs, the smallest number is given first. When the error is cleared, the next error number is given.
Example: If errors occur for download settings 10 and 12, the Response Flag will be e010.
An OR of 8000 and the operation command code is given. If a setting range error occurs at the same time,
indicating the operation command error will be given priority.
Example: If an error occurs for operation command code 1101, the Response Flag will be 9101.
z Precautions for AT (Auto-tuning)
Do not change the set values in the download area from the start of auto-tuning until auto-tuning is
completed or canceled. Programless communications cannot be used to change the set values of
the E5@C after auto-tuning starts. Also, if the Request Flag is set to 1 (Enable Writing) at the completion of auto-tuning, the set values in the download area are initialized to the set values from the
E5@C. This is to update the PID constants. (It occurs even if PID constants are not set in the download area.) To prevent initialization, change the Request Flag to 0 (Disable Writing) after auto-tuning
starts. If you change the Request Flag to 1 (Enable Writing) after the completion of auto-tuning, the
values in PLC memory will be written to the E5@C. If you change the Request Flag to 2 (Initialize
Download Areas) after the completion of auto-tuning, the download area will be initialized with the
set values from the E5@C.
z Precautions for ST (Self-tuning)
If you use self-tuning and set PID constants in the download area, always leave the Request Flag
set to 1 (Enable Writing).* If you change the Request Flag from 0 (Disable Writing) to 1 (Enable Writing) during operation, the PID constants that were found with self-tuning will be overwritten with the
values from PLC memory.

Confirming Operation of Programless Communications
You can check the operation of programless communications in the Communications Status in the
upload area.
The value of the Communications Status changes between 0 and 1 each time the upload area is
updated.
6-3-6
Write Mode
The E5@C normally writes the set values to non-volatile memory (i.e., in Backup Mode). If you frequently change set values with programless communications, use an operation command to change to
RAM Write Mode.
In RAM Write Mode, however, the set values will be restored to the values in non-volatile memory every
time the power supply is cycled. If you need to maintain the current set values before the power supply
is turned OFF, use an operation command to save them to RAM before the power supply turns OFF.

E5@C Controller Setup
This section describes the setup for programless communications (or components communications).
Refer to 6-2 E5@C Setup for the procedure to display parameters. (Refer to 7-1-3 E5@C Setup for component communications as well.) Here we will assume that all parameters other than those for communications have already been set. Make sure that all of the E5@C Controllers are the same model. The
parameter settings cannot be copied if the models are different.
(2) Change the parameter settings in the communications setting level of the No. 0
Controller to the values that are given below.
6-4 Connecting to CP-series PLCs
(1) Set the Communications Unit No. parameter (u-no) in the communications setting
level to 1 for the No. 1 Controller and set it to 2 for the No. 2 Controller. Leave the
other communications settings at their default values.
The default communications unit number is 1, so the Communications Unit No. parameter
for the No. 1 Controller does not need to be changed.
Always set the communications unit numbers of the slaves in order from 1.
To enable the changes to the settings, always return to the operation level.
6
Do not return to the operation level even after you finish making the settings.
Here we will assume that all parameters other than those for communications have already
been set. If parameters other than those for communications need to be set, change them
first and then change the communications settings last.
(3) Perform the following procedure to copy the parameter settings in the No. 0
Controller to the No. 1 and No. 2 Controllers.
(a) Display the copy parameter in the communications setting level on the No. 0
Controller.
(b) Press the Up Key to select all and wait for three seconds. The completion of the
copy operation must be confirmed, so do not move to any other levels or parameters. If you do change to any other levels or parameters, display the copy
parameter again.
(c) The PV displays on the No. 1 and No. 2 Controllers will change to copy and then
these Controllers will be reset.
(d) Confirm that the setting of the copy parameter on the No. 0 Controller changes
to off (i.e., copying completed), and then return the No. 0 Controller to the
operation level.

Introduction
You can use component communications to connect two or more E5@C Controllers via RS-485 and
then change the set points or RUN/STOP status for all of the Controllers at the same time. If you
change the set point or RUN/STOP status of the master (i.e., the Controller with a communications unit
number of 0), the set points or RUN/STOP status of all of the slaves (i.e., the Controllers with communications unit numbers other than 0) that are connected via RS-485 will change automatically. When you
change the set points, the set point from the master can be multiplied by a factor or offset at each slave.
You can also copy the parameter settings in the master to the slaves.
All slaves from 1 to n are
automatically changed in
order to RUN status.
Master changed to
RUN status.

SP Calculations
The set point (SP) of a slave can be calculated from the set point of the master as shown below. The
slave performs the calculation only during operation. The value is not written to the slave if it exceeds
the set point limiter.
During operation: Slave SP = Master SP × SP Slope + SP Offset
When stopped: Slave SP = Master SP

For component communications, the master sends the value in order starting from slave 1. There will
be a delay of up to 30 ms between when the set point or RUN/STOP status is sent to all of the slaves. If
this delay is too long, consider using event inputs to change the set points or to change the RUN/STOP
status.
If communications with a slave fail, the master will retry communications twice. If communications still
fail, it will move to processing the next slave. To see if the value was sent correctly, check the display of
the Set Point or STOP parameter on each slave.

Slaves
• If the multi-SP is changed, the set point is sent to each slave.
• This function is disabled in the following cases:
• During operation with a remote SP
• When changing the set point for SP tracking
• SPs are not calculated when operation is stopped.
• The value from the master is not received in the following cases.
• When the set point from the master or the results of set point calculation exceeds the set
point limiter of the slave.
• When Communications Writing parameter is set to “OFF”
• When RUN/STOP is assigned to an event input (Changes in the set point will be
received.)
• When a communications error occurs three times in a row

If the set point or the RUN/STOP status is changed at the master, the new value is sent to the slaves
starting with the slave with communications unit number 1 and continuing on to the slave with the highest communications unit number. The master sends values only during operation. Values are not sent
while in the initial setting level.
If the set point or the RUN/STOP status is changed again while sending a previous value to the slaves,
the original value will not be transferred correctly. Always wait for a value to be sent to all of the slaves
before you change the set point or RUN/STOP status again.
7 Component Communications

Troubleshooting
Possible problems that can occur with component communications and corrective actions are given in
the following table.
Status
The set point or RUN/STOP status
will not change for a slave (i.e., a
Controller with a communications
unit number other than 0).
The set points or the RUN/STOP
status will not change for any of the
slaves.
The set point is not calculated.
It is sometimes not possible to
change the set points or RUN/STOP
status.
Cause and corrective action
The wiring to the slave is not correct.
The communications settings for the slave are not
correct.
• The Protocol Setting parameter is not set to cmp.
• The Communications Unit No. parameter is set to
the same value as another slave.
• The setting of the Communications Baud Rate
parameter is not the same as the other slaves.
• The Highest Communications Unit No. parameter
is not set to the highest communications unit
number that is actually set.
• The Communications Writing parameter is set to
OFF.
◆ When the RUN/STOP Does Not Change
RUN/STOP is assigned to an event input for the
slave.
◆ When the Set Point Does Not Change
The set point from the master or the results of set
point calculations exceeds the set point limiter of the
slave.
The wiring to the master (i.e., the Controller with
communications unit number 0) is not correct.
The communications settings in the master are not
correct.
• The Protocol Setting parameter is not set to cmp.
• The Communications Unit No. parameter is not set
to 0.
• The Communications Baud Rate parameter is not
set to the same value as the slaves.
• The Highest Communications Unit No. parameter
is not set to the highest communications unit
number that is actually set.
• The SP Slope or SP Offset parameter is not set
correctly.
• The set point was changed at the master when the
slave was stopped (setting area 1).
There may be noise interference. Connect
terminating resistance to both ends of the
communications line.

A-2 Troubleshooting
Before Requesting Repairs
If communications are not functioning properly, check the items in the following table before requesting
repairs. If normal operation cannot be restored even after checking everything, return the product to
your OMRON representative.
Problem: Communications are not possible or communications errors occur.
Item
The communications wiring is not
correct.
The communications line has
become disconnected.
The communications cable is
broken.
The communications cable is too
long.
The wrong communications cable
has been used.
The specified power supply
voltage is not being supplied to
the Controller.
The specified power supply
voltage is not being supplied to
an Interface Converter (e.g., the
K3SC).
The same baud rate and
communications method are not
being used by all of the
Controllers, host devices, and
other nodes on the same
communications line.
The unit number specified in the
command frame is different from
the unit number set for the
Controller.
The same unit number as the
Controller is being used for
another node on the same
communications line.
There is a mistake in
programming in the host device.
The host device is detecting the
absence of a response as an
error before it receives the
response from the Controller.
Page
Correct the wiring.
1-4
Connect the communications line securely and tighten the
screws.
Replace the cable.
---
The total cable length is 500 m maximum for RS-485
communications.
Use a shielded, AWG24 to AWG18 (cross-sectional area of
1-4
0.205 to 0.823 mm2) twisted-pair cable for the
communications cable.
When 1:N, RS-485 communications are used, a maximum
of 32 nodes may be connected, including the host node.

Set or connect terminating resistance at each end of the
line. If the E5@C is the end node, 120-Ω (1/2-W)
terminating resistance is used. Be sure that the combined
resistance with the host device is 54 Ω minimum.
Supply the specified power supply voltage.
---
Supply the specified power supply voltage.

The host device is detecting the
absence of a response as an
error after broadcasting a
command or sending a software
reset command.
The host device sent another
command before receiving a
response from the Controller.
The host device sent the next
command too soon after
receiving a response from the
Controller.
The communications line became
unstable when the Controller’s
power was turned ON or
interrupted, and the host device
read the unstable status as data.
The communications data was
corrupted by noise from the
environment.
The Controller does not return responses for broadcast or
software reset commands.
2-2
2-17
4-2
4-14
Always read the response after sending a command
(except for broadcast or software reset commands).
---
Wait for at least 2 ms after receiving a response before
sending the next command.
1-2
Initialize the reception buffer in the host device before
sending the first command and after turning OFF the
power to the Controller.
---
Try using a slower baud rate.
Separate the communications cable from the source of
noise.
Use a shielded, twisted-pair cable for the communications
cable.
Use as short a communications cable as possible and no
not lay or loop extra cable.
Do not run the communications cable parallel to a power
line to prevent inductive noise.
If noise countermeasures are difficult to implement, use an
Optical Interface.
